REW in plain words
Three months to Sep 30, 2026: REW returned −12.8% where its own daily promise gave −15.0%, 2.1 points over. Read the multiple against the whole window instead and −2 times XLK's 5.6% implies −11.2%, which makes REW look 1.7 points short. 3.8 of that is daily compounding, which happens to any −2 times fund over the same path, and the rest is the fund. REW aims to return -2 times XLK's move each day, then resets. Over one day it does that. Over longer, the daily results compound, so the total is not -2 times the period's move: in a market that falls and comes back it is reliably less, and in a steady run it can be more. XLK moved at 26% annualized over that window. That is what decides how far the two figures separate: the same fund on a calm underlying and a violent one is a different product.
XLKX in plain words
Three months to Sep 30, 2026: XLKX returned +7.0% where its own daily promise gave +9.6%, 2.5 points short. Read the multiple against the whole window instead and 2 times XLK's 5.6% implies +11.2%, which makes XLKX look 4.1 points short. 1.6 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. XLKX aims to return +2 times XLK's move each day, then resets. Over longer, the daily results compound, so the total is not +2 times the period's move: in a market that falls and comes back it is reliably less, and in a steady run it can be more.
Questions people ask
- Which came closer to its stated multiple, REW or XLKX?
- Over the window to Sep 30, 2026, REW finished 1.7 points from what its multiple implies and XLKX finished 4.1 points from its own, so REW came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are REW and XLKX levered on the same thing?
- Yes. Both are levered on technology, REW at -2 times and XLKX at +2 times the daily move.
- Which one decays faster, REW or XLKX?
- Decay follows how much the underlying moves about. Over this window REW’s moved at 26% annualized and XLKX’s at 26%, so REW has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold REW or XLKX for a year?
- Both reset every day, so the multiple in the name applies to a single day and the daily results compound. Over a year the total is not the multiple times the year’s move, and in a market that falls and comes back it is reliably less. ETFIQ makes no recommendation either way.
